Filed: 1988-12-27
Abstract: PURPOSE:To easily confirm and specify a set point by storing the starting point and the finishing point of repetition even after a power source is turned off and displaying them on a television screen. CONSTITUTION:The set value of the set point held in a storage control circuit 2 by an operation input circuit 1 is displayed on the television 9 through a display control circuit 4 by a display circuit 5. The set value which should be set is inputted by the circuit 1 and held in the circuit 2, then displayed on the television 9. The function of repetitive reproduction is operated to be actuated by the circuit 1. A control circuit 6 is instructed to actuate the function of repetitive reproduction through the circuit 2, compares the set value of the circuit 2 with the set value on a magnetic tape and performs the repetitive reproduction. The circuit 2 stores the actuation state of the reproducing function. When a power source is turned off, the circuit 2 detects the stoppage and switches to backup by a battery 3, then instructs the circuit 6 so that the device is in a state before stoppage when the power source is recovered. Thus, setting can be performed regardless of the position of the magnetic tape and the set point can be easily confirmed. Moreover, the set point is easily specified from a third person.

Title: Node degree mechanism for heater controller of vehicle rotation dial-system and assembly method of node degree mechanism
Inventor: MAEDA YASUSHI
IPC: G05G1/00
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To arrange a sliding way which does not adversely affect illumination on a face side and to reduce the man-hour of inspection by arranging ribs for inserting a ball in a face position at the time of node degree assembly. SOLUTION: A sliding way for inserting a ball 22 into a guide arm 21 is formed of two ribs 26 having reflection faces reflecting light in the same way as a reflection face 31. The ribs 26 are arranged so that the ball rotates toward a ball stop groove part 24a corresponding to the symbol mark of a face being the position of a dial knob at the time of storage. The ribs 26 have roles as guides for leading the ball 22 to the ball stop groove part 24a. Since a mortar- like slope is arranged in the reflection face 31, the ball 22 naturally rolls the slope and is led to the groove part 24a. Since the ribs 26 themselves have the reflection faces, a shadow is difficult to occur, the symbol mark of the face on the surface of a display panel does not become dark and visibility is secured.

Title: Picture tube device
Inventor: KAWASAKI MASAKI
IPC: H01J31/10
Filed: 1989-12-21
Abstract: PURPOSE:To reduce adverse effect on beam focusing function by making the diameter of a deflection yoke attachment area smaller than that of an electron gun sealing area and arranging an annular magnetic piece for shunting magnetic field leakage from the deflection yoke at the open end of a cylindrical magnet for electromagnetic focusing. CONSTITUTION:The outer diameter (d) at the deflection yoke attachment area of the neck portion of a glass housing 2 is smaller than the outer diameter of the electron gun sealing area 14. A first and a second annular magnetic pieces 9, 10 are coaxially attached to both open ends of a cylindrical magnet 8 respectively having at its axial ends N pole and S pole, and give electromagnetic focusing effect on an electron beam passing therethrough. The magnetic field leakage out of a deflection yoke 12 to an electron gun is shunted with the first and second annular magnetic pieces 9, 10. This prevents the leakage magnetic flux from entering the electron gun area and reduces adverse effect on the beam focusing. This also reduces the overall size of a device by reducing the distance between the deflection yoke and the electron gun. Since the focused magnetic field is distributed more uniformly, aberration is reduced.

Filed: 1992-12-15
Abstract: PURPOSE:To obtain an oxide ion conductive body having high ion conductivity and high mechanical strength against heat cycle by adding Sc as a main dopant and Al as a sub dopant in a specific range. CONSTITUTION:A raw material is prepared to mix in accordance with a chemical composition expressed by a formula (1-x-y)ZrO2-xSc2O3-yAl2O3 (where, 0.07<=(x+y)<=0.13 and 0.005<=y<=0.02), is molded into a pellet having a prescribed size and is fired in air at about 1620 deg.C for about 60 hours to form the oxygen ion conductive body. The oxygen conductive body contains Sc as the main dopant. Since the ion radius of Sc is closer to that of Zr, the oxide ion easily moves then Y2O3 stabilized ZrO2 (YSZ), extremely large ion conductivity is attained at a lower temp. compared with YSZ. And Al stable in trivalent is added as the sub dopant. As a result, the ion conductivity keeps almost the property of Sc and the crystal structure stable in hexagonal system does not exhibit crystal transformation.
